Properties¶

abstract val context:

open val <Root, Type> KProperty1<Root, Type>.field: Field<Root, Type>

Converts a Kotlin property into a Field.

open fun <R : Any, T> cond(condition: Value<R, Boolean>, ifTrue: Value<R, T>, ifFalse: Value<R, T>): Value<R, T>

Decides between two values depending on the evaluation of a boolean value.

open operator fun <Context : Any, Root, Child> Value<Context, Root>.div(field: KProperty1<Root, Child>): Value<Context, Child>

Refers to field as a nested field of the current value.

open operator fun <Context : Any, Root, Child> Value<Context, Root>.div(field: Field<Root, Child>): Value<Context, Child>

Refers to field as a nested field of the current value.

open operator fun <Root, Parent, Child> KProperty1<Root, Parent>.div(child: KProperty1<Parent & Any, Child>): Field<Root, Child>

Refers to child as a nested field of the current field.

open operator fun <Root, Type> KProperty1<Root, Collection<Type>>.get(index: Int): Field<Root, Type>

Refers to a specific item in an array, by its index.

open operator fun <Root, Type> KProperty1<Root, Map<String, Type>>.get(index: String): Field<Root, Type>

Refers to a specific item in a map, by its name.

open fun <Result> of(value: Result): Value<Any, Result>

Refers to a Kotlin value within an aggregation value.

open fun of(value: ): Value<Any, >

Refers to a BsonType within an aggregation value.

open fun <Context : Any, Result> of(field: KProperty1<Context, Result>): Value<Context, Result>

open fun <Context : Any, Result> of(field: Field<Context, Result>): Value<Context, Result>

open fun <R : Any, T> switch(vararg cases: <Value<R, Boolean>, Value<R, T>>, default: Value<R, T>? = null): Value<R, T>

Selects one value based on multiple conditions.
